Sub-dividers to hold miniatures

I picked up a thread box to hold miniatures and wanted to get the most out of it. Roughly half of my minis stand upright, allowing three 28mm minis per compartment. The other half are just a bit too tall, so they lie on their sides, with the angled divider allowing for two per compartment.

These were made to go with this Double Sided Organizer from CreativeOptions. The compartment dimensions are 38mmX79mmX38mm. I found it at Walmart.
